Hi I tried asking this question yesterday but still had some confusion.Since the area must be in cm^2.
IP The weight of your 1440 kg car is supported equally by its four tires, each inflated to a gauge pressure of 30.0 lb/in^2 .
What is the area of contact each tire makes with the road?
What gauge pressure is required to give an area of contact of 122 for each tire?

OK i have one attempt left, first i change the gauge pressue to newton/m^2? And since P= F/A solve for A after making f = 1440*g? Theni have to divide it by 4 for every tire? but im having trouble with conversions, and my final answer being in cm^2. SOOO confused
